Wiring issues can result in intermittent power supply. Check the wiring to ensure there are no loose or damaged connections. If you notice any frayed wires, it’s best to consult a professional.
2. Wall Control Malfunction
If your wall control isn’t responding, it may be faulty or miswired. Check the wiring connections and, if necessary, try replacing the wall control unit.
3. Limit Setting Adjustments
Your LiftMaster garage door opener has limit settings that control how far the door opens and closes. If these settings are off, your door may not reach the intended positions.
- To adjust the limit settings, locate the adjustment dials on your opener and follow the instructions in your user manual.
- Make small adjustments and then test the door to ensure it’s operating correctly.
